Certify your project

Are you an entrepreneur removing carbon with nature who wants to sell carbon credits? Like a bio-based builder, regenerative farmer, enhanced weathering pioneer, or seaweed grower?

Most carbon certification schemes are complex and expensive. ONCRA offers simple, reliable and efficient carbon removal certification. We work from plain measurements in your fields or production processes. If you bring your carbon measurement data and proof of ownership, ONCRA accounts for your carbon credits, trustworthy, fast, and at a reasonable cost.

Note that all Removers will be subject to strict ‘Know-Your-Customer’ background checks.

Creating Carbon Removal Credits is a
3-step process

ONCRA is open source and based on established and scientifically proven methods. We follow a strict 3-step process of quantification, certification and verification.


Use our open calculation estimation model to gather your real life data and work out your business case. Do not hesitate to contact us if you need help.
The more accurately you quantify your removal, the greater the chance that your project will be positively assessed.


Enter your project data to receive a draft verification report. You may use all established accounting methods available in our repository
After agreeing to a positive verification, our team will contact you to set up an ONCRA Carbon Accounting Agreement (OCAA).


All provided data will be empirically verified, and an MRV Protocol will be followed to keep track of your actual removal. You must track sales of credits on our ledger, but can sell them anywhere. And only after you sell credits, buyers pay verification costs through a fee to cover certification costs included in the sales price.

“By performing a ‘doughnut check’ we evaluate if the project operates within the planetary boundaries. Multiple benefits like biodiversity, clean water and meaningful jobs, are examples of how ONCRA removal credits tick many SDGs and result in a holistic approach.”
